(a) The department store marks up the wholesale price by 70%, which means they are selling the television for $569 + 70% of $569 = $569 + $398.30 = $967.30. However, Kevin gets a 10% discount, which means he would pay 90% of the in-store price: 0.9 x $967.30 = $870.57. Therefore, Kevin would pay $870.57 for the television at the department store.
(b) The superstore marks up the wholesale price by 60%, which means they are selling the television for $569 + 60% of $569 = $569 + $341.40 = $910.40. Since Kevin is not a member of the superstore's customer loyalty program, he would have to pay the full in-store price of $910.40. Therefore, Kevin would pay $910.40 for the television at the superstore.
(c) Kevin would pay more for the television at the department store.
